Abstract
Description
Beinprothese zur Adaption an einen Oberschenkelstumpf Leg prosthesis for adaptation to a thigh stump
Beschreibungdescription
Die vorliegende Erfindung betrifft eine Beinprothese zur Adaption an einen Oberschenkelstumpf, bestehend aus einem intramedullar im Femurstumpf zu verankernden Adapter für ein extrakorporal ankoppelbares Kniegelenk und einer am Kniegelenk angekoppelten Unterschenkelprothese.The present invention relates to a leg prosthesis for adaptation to a thigh stump, consisting of an adapter to be anchored intramedullarily in the femur stump for an extracorporeally connectable knee joint and a lower leg prosthesis coupled to the knee joint.
Eine derartige Beinprothese ist beispielsweise bekannt aus der DE-C-198 45 191.Such a prosthetic leg is known for example from DE-C-198 45 191.
Mit dieser Beinprothese wird das Ziel verfolgt, die sogenannte Osteoperzeption des oberschenkelamputierten Patienten entscheidend zu verbessern, dadurch, daß ein intramedulläres Stielteil des Adapters in den Femurstumpf eingesetzt wird und dort aufgrund einer offenmaschigen, dreidimensionalen Oberflächenstruktur mit dem natürlichen Knochenmaterial verwächst, also eine sehr innige Verbindung zwischen dem Implantat einerseits und dem natürlichen Knochen andererseits angestrebt wird.The aim of this leg prosthesis is to decisively improve the so-called osteoperception of the thigh-amputated patient by inserting an intramedullary stem part of the adapter into the femoral stump and growing there with the natural bone material due to an open-meshed, three-dimensional surface structure, i.e. a very intimate connection between the implant on the one hand and the natural bone on the other.
Die Verbindung zwischen dem Adapter und dem natürlichen Knochen kann sich allerdings als so fest herausstellen, daß eben diese an sich gewünschte Festigkeit zu Problemen führen kann, wenn es nämlich um äußergewöhnliche Kraftbelastungen geht. So ist es nicht von vornherein auszuschließen, daß eine extreme, beispielsweise Scherbelastung des künstlichen Kniegelenkes oder eine Belastung der Unterschenkelprothese in den intramedullar verankerten Adapter im Femurstumpf weitergeleitet wird und dort zu Brüchen führen kann. Diese Situation ist für den Patienten nicht akzeptabel.The connection between the adapter and the natural bone can, however, turn out to be so firm that it is precisely this strength that is inherently desired, which can lead to problems when it comes to exceptional force loads. So it cannot be ruled out from the outset that extreme, for example shear stress on the artificial knee joint or a load on the lower leg prosthesis in the intramedullary anchored adapter is forwarded in the femoral stump and can lead to fractures there. This situation is not acceptable to the patient.
Im Rahmen der vorliegenden Erfindung gilt es daher, dieses Problem bei einer gattungsgemäßen Beinprothese zu lösen.In the context of the present invention, it is therefore a matter of solving this problem in a leg prosthesis of the generic type.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine extrakorporal angeordnete Sollbruchstelle in mindestens einem Prothesenteil der Bemprothese vorgesehen ist, welche durch Sollbrechen bei einer vorbestimmten Kraft das Prothesenteil abbrechen läßt.This object is achieved in that an extracorporeally arranged predetermined breaking point is provided in at least one part of the prosthesis prosthesis, which breaks the prosthesis part by predetermined breaking at a predetermined force.
Wesentlich hierbei ist, daß die Sollbruchstelle in einem der Prothesenteile extrakorporal anzuordnen ist, damit in einem Unglücksfalle keine inkorporalen Teile der Beinprothese bzw. Teile des Oberschenkelstumpfes in Mitleidenschaft geraten.It is essential here that the predetermined breaking point in one of the prosthesis parts is to be arranged extracorporeally, so that in the event of an accident, no incorporeal parts of the leg prosthesis or parts of the thigh stump are affected.
Gemäß einer vorteilhaften Ausführungsform ist vorgesehen, daß die Sollbruchstelle im Bereich der Ankopplung des Kniegelenks an den intramedullar verankerten Adapter angeordnet ist. Dies geschieht vorzugsweise durch Anordnung einer Sollbruchstelle in einem Zwischenstück zwischen Adapter und Kniegelenk, damit der dauerhaft implantierte Adapter selbst nicht in Leidenschaft gezogen wird, sollte es einmal aufgrund außergewöhnlicher Kraftbelastungen zum Aufbrach der Sollbrachstelle kommen.According to an advantageous embodiment it is provided that the predetermined breaking point is arranged in the area of the coupling of the knee joint to the intramedullary anchored adapter. This is preferably done by arranging a predetermined breaking point in an intermediate piece between the adapter and the knee joint, so that the permanently implanted adapter itself is not pulled with passion should the predetermined breaking point break open due to extraordinary force loads.
Gemäß einer anderen Ausfuhrungsform ist vorgesehen, daß die Sollbrachstelle im Bereich einer Seitenführung des Kniegelenks angeordnet ist. Die Seitenführung bildet dabei die Funktion der natürlichen Seitenbänder ab. Sollte es aufgrund spezifischer Belastungen zu einer Überhöhung der zulässigen Belastung kommen, so würde die im Bereich der Seitenführung vorgesehene Sollbruchstelle für eine schlagartige Entlastung der übrigen Beinprothese kommen. Alternativ hierzu ist eine Ausführungsform vorgesehen, bei der die Sollbruchstelle im Bereich der Ankopplung des Kniegelenks an die Unterschenkelprothese angeordnet ist.According to another embodiment, it is provided that the intended fallow site is arranged in the region of a side guide of the knee joint. The side guide represents the function of the natural side bands. Should the permissible load be increased due to specific loads, the predetermined breaking point provided in the area of the lateral guide would result in a sudden relief of the rest of the leg prosthesis. As an alternative to this, an embodiment is provided in which the predetermined breaking point is arranged in the region of the coupling of the knee joint to the lower leg prosthesis.
Die Entscheidung hierüber, wo die Sollbrachstelle tatsächlich angeordnet wird, hängt unter anderem beispielsweise davon ab, welche Teile besonders kostspielig sind und daher möglichst nicht einem Aufbrechen unterworfen werden sollen. Bei einem einfachen Scharniergelenk als Kniegelenk mag die Anordnung der Sollbrachstelle im Bereich der Ankopplung des Kniegelenks an die Unterschenkelprothese wünschenswert sein. Bei Einsatz eines relativ aufwendigen Kniegelenks, beispielsweise wie es sich aus der EP-0 358 056 Bl ergibt, käme sicherlich die Anordnung der Sollbrachstelle im Bereich der Ankopplung des Kniegelenks an den Adapter in Betracht.The decision as to where the intended fallow site is actually located depends, among other things, on which parts are particularly expensive and therefore should not be broken open, if possible. In the case of a simple hinge joint as a knee joint, the arrangement of the predetermined breaking point in the region of the coupling of the knee joint to the lower leg prosthesis may be desirable. If a relatively elaborate knee joint is used, for example, as is apparent from EP-0 358 056 B1, the arrangement of the predetermined breaking point in the area of the coupling of the knee joint to the adapter would certainly be considered.
Besonders bevorzugt ist die Ausführung der Sollbrachstelle als Materialschwächung in dem betroffenen Bereich. Dies ist durch eine relativ einfache Maßnahme, wie eine zusätzliche Ausfräsung, relativ einfach zu realisieren.It is particularly preferred to carry out the predetermined break point as a material weakening in the affected area. This can be achieved relatively easily by a relatively simple measure, such as an additional milling.
Es ist jedoch gemäß einer vorteilhaften Weiterbildung auch möglich, mehrere Sollbrachstellen in unterschiedlichen Prothesenteile vorzusehen, die jeweils so ausgeführt sind, daß jede einzelne Sollbrachstelle auf jeweils eine andere spezifische Belastung anspricht. So ist es möglich, beispielsweise im Bereich einer Seitenführung des Kniegelenks eine Sollbruchstelle vorzusehen, die bei extremen lateral-medialen Beansprachungen anspricht, d. h. abbricht, und zum anderen eine Sollbrachstelle im Bereich der Ankopplung des Kniegelenks an den Adapter, welche beispielsweise auf dorsal-ventrale Belastungen anspricht.However, according to an advantageous further development, it is also possible to provide a plurality of predetermined breaking points in different prosthesis parts, each of which is designed such that each individual predetermined breaking point responds to a different specific load. It is thus possible, for example, to provide a predetermined breaking point in the area of a lateral guide of the knee joint which responds to extreme lateral-medial demands, i.e. H. breaks off, and on the other hand a predetermined breaking point in the area of the coupling of the knee joint to the adapter, which responds, for example, to dorsal-ventral loads.
Vorteilhaft ist es, die Sollbrachstellen so auszuführen, daß diese bei Belastungskräften im Bereich von 150 bis 500 Kp abbrechen. Dies simuliert in etwa die Kräfte, die in einem natürlichen Bein Reaktionen beispielsweise im Kniebereich auslösen, bietet jedoch noch hinreichend Reserve vor dem Hintergrund der spezifischen Probleme der Beinprothese, bei welcher eben eine Belastung im Knie oder Unterschenkelbereich zu einem Brach im Oberschenkelbereich führen kann aufgrund der intramedullären Verankerung des erwähnten Adapters.It is advantageous to carry out the intended fallows so that they break off under load forces in the range from 150 to 500 Kp. This roughly simulates the forces that occur in a natural leg, for example in reactions Trigger knee area, however, still offers sufficient reserve against the background of the specific problems of the leg prosthesis, in which a load in the knee or lower leg area can lead to a fracture in the thigh area due to the intramedullary anchoring of the adapter mentioned.
Die Erfindung wird anhand eines Ausführungsbeispiels gemäß der Zeichnungsfiguren näher erläutert. Hierbei zeigt:The invention is explained in more detail using an exemplary embodiment according to the drawing figures. Here shows:
Fig. 1 einen schematischen Überblick über die Beinprothese, undFig. 1 is a schematic overview of the prosthetic leg, and
Fig. 2 eine Vergrößerung der Ansicht der Beinprothese im Bereich des Kniegelenkes der Prothese aus Fig. 1.FIG. 2 shows an enlargement of the view of the leg prosthesis in the area of the knee joint of the prosthesis from FIG. 1.
Nachfolgend sind die gleichen Teile mit denselben Bezugszeichen bezeichnet.The same parts are designated with the same reference symbols in the following.
Den ersten Überblick verschafft Fig. 1. Mit dem Oberschenkel 1 ist über ein intramedullar verankerter Adapter 7 ein künstliches Kniegelenk 3 verbunden, welches seinerseits mit einer Unterschenkelprothese 4 gekoppelt ist. Der Übergangsbereich zwischen Unterschenkelprothese 4 und dem Oberschenkelstumpf 1 ist bedeckt mit einer Schutzmanschette 8.FIG. 1 provides the first overview. An artificial knee joint 3 is connected to the thigh 1 via an intramedullary anchored adapter 7, which is in turn coupled to a lower leg prosthesis 4. The transition area between the lower leg prosthesis 4 and the thigh stump 1 is covered with a protective sleeve 8.
Wie aus Fig. 2 hervorgeht, ist im Bereich der Ankopplung des Kniegelenks 3 an den Adapter 7 eine Sollbrachstelle 5 in Form einer Materialschwächung des am Adapter 7 angeflanschten Teils des Kniegelenks 3 vorgesehen. Diese Sollbruchstelle kann beispielsweise durch eine Ausfräsung, d. h. eine Materialschwächung des angeflanschten Teils realisiert sein, vorzugsweise so, daß diese bei auftretenden Belastungskraften in Höhe von 150 bis 500 Kp abbricht, so daß derartige Belastungen über den Adapter 7 nicht in den Oberschenkelstumpf 1 , und dort insbesondere in den Femurstumpf eingeleitet werden. In Ergänzung oder alternativ hierzu ist eine weitere Sollbrachstelle 5 in einer Seitenführang 6 des speziell ausgebildeten Kniegelenks 3 vorgesehen. Diese Sollbruchstelle ist insbesondere dafür vorgesehen, bei einen bestimmten Grenzwert überschreitenden lateral-medialen Belastungskräfte aufzubrechen, um Schaden vom Femurstumpf abzuwenden.As can be seen from FIG. 2, in the area of the coupling of the knee joint 3 to the adapter 7 a predetermined breaking point 5 is provided in the form of a material weakening of the part of the knee joint 3 flanged onto the adapter 7. This predetermined breaking point can be realized, for example, by milling, that is, weakening the material of the flanged part, preferably in such a way that it breaks off when load forces occur in the amount of 150 to 500 kgf, so that such loads are not passed through the adapter 7 into the thigh stump 1 and there in particular be introduced into the femoral stump. In addition or as an alternative to this, a further predetermined fallow site 5 is provided in a side guide 6 of the specially designed knee joint 3. This predetermined breaking point is intended in particular to break open when the lateral-medial loading forces exceed a certain limit value in order to avert damage from the femoral stump.
Aufgrund der Kombination mehrfacher Sollbrachstellen läßt sich ein individuelles Bruchverhalten der Beinprothese realisieren. Due to the combination of multiple predetermined breaking points, an individual fracture behavior of the leg prosthesis can be realized.
